I have my 5508's in a HA/SSO pair and am being faced with an upgrade from 8.3.135.0 to 8.3.140.0. Does the upgrade occur with NO network downtime, or do I need to plan an outage?
The upgrade document doesn't cover any HA deployments.
Roughly 350 WAP on the pair; mix of 1142, 3502, 3602, and 3702 devices.
Thank you for your help.

Zechariah,
I understand, but the process has not changed since the release of that document. Below is a listing from the 8.3 configuration guide regarding the upgrade process in an HA environment.
The following is a list of some software upgrade scenarios:
Thanks!

See this document. You'll need to reload the APs and controllers so downtime will be unavoidable.

That document is from 2015 and 7.3/4 release. Wasn't sure if 8.3 code had matured enough to do an in-place upgrade.

Thanks Team. One day they will support in-service I hope.

No kidding. The wireless team should have a meeting with the team in charge of the ASA, which has supported zero-downtime HA upgrades for well over a decade. I'm sure there's some technical reason why it's so much more difficult with a WLC... oh well.

Hi Zechariah,
i recommend you, take a downtime and do the upgrade...
